Flame lamination is described as changing the surface of a material to a molten state and rapidly cooling to perform a cohesive bond. It is one of the most effective methods of bonding foams and other materials like papers, films, and fabrics.
Flame lamination involves exposing a piece of material to an open flame to create a thin layer of molten polymer on the surface. Another substrate is then brought into contact with the layer. It then cools, compressing the two materials and allowing them to bond together.
How does it work?
Polyurethane foam is heated using a controlled flame. Another substrate will then be directly contacted with the foam using controlled tension and pressure. The flam lamination process involves bonding a foam and textile together while the molten foam cools down rapidly. The strength between the foam and the substrate is determined by the speed and distance at which the foam passes through the controlled flame.

The Advantages of Flame lamination
Flame lamination is low cost and a highly efficient service.
It does not require an adhesive – eliminating the risk of bond failure, as well as cost savings.
Flame lamination process is also a lot faster than alternative laminating processes.
Flame lamination can be performed on a wide range of materials
Because there is no need for an adhesive, the materials are a lot easier to recycle, making it a far more environmentally friendly alternative to other methods.
Composites can be created on one side of the core or both sides of the core.
Composites can be of variable thickness.
Flame lamination has a large amount of uses and can be used to create custom composites for foam, films, and knit. As well as:
- Car interiors
- Medical disposables
- Intimate wear
- Orthopaedic padding
- Beverage insulating
- Thermal/acoustic insulation
